Some of you may remember this boat. A stereo company made it thier demo boat and used Hertz Audio for all the seperates in the boat. As you can see they have them firing up and the speakers are a paper cone. My buddys daughter just bought this boat (sans the wetsounds on the tower) she is like 20 and will likely have friends jumping in and out of the boat getting these wet. Any ideas on a spray you could apply to them that would lend some level of protection from water damage?
